Header Manifold Blanket: High-Performance Thermal Protection for Exhaust Systems

The Header Manifold Blanket is an advanced heat management solution engineered to improve engine bay temperatures and performance by effectively insulating exhaust headers and manifolds. Its flexible design allows for quick, tool-free installation—simply secure it using integrated clips along the top section of the header.

Crafted with a heat-resistant fabric interior capable of withstanding direct exposure up to 1000°F, this blanket faces toward the exhaust source to contain and reflect heat back into the exhaust stream, promoting scavenging efficiency and reducing under-hood temperatures. The outer layer is aluminized, offering superior protection against radiant heat up to 2000°F, abrasion, and fluids such as oil or coolant.

Application Examples:

• In high-performance V8 engines, using two 20" x 24" blankets helps minimize heat soak, preserving intake air density and supporting consistent power output.

• For turbocharged 4-cylinder applications, the 36" x 40" blanket shields sensitive components like alternators and brake lines from extreme radiant heat, enhancing reliability.

Available in two size options, the blanket is an essential upgrade for both race and street vehicles seeking thermal management and component protection.
